On July 1, 2001, a nationwide law in Portugal took effect that decriminalized all drugs, including cocaine and heroin. Under the new legal framework, all drugs were "decriminalized," not "legalized." Thus, drug possession for personal use and drug usage itself are still legally prohibited, but violations of those prohibitions are deemed to be exclusively administrative violations and are removed completely from the criminal realm. Drug trafficking continues to be prosecuted as a criminal offense.
The data show that, judged by virtually every metric, the Portuguese decriminalization framework has been a resounding success. Within this success lie self-evident lessons that should guide drug policy debates around the world.
